Title: Method and apparatus for exposing resist
Inventor: SATO MASAHIRO
IPC: H01L21/027
Filed: 1985-10-03
Abstract: PURPOSE:To improve the non-defective rate of resist films when used in the manufacturing steps of a superhigh LSI by varying an interval between a mask and the resist films during exposure to avoid a fixed interference fringes to expose the resist films. CONSTITUTION:When a solenoid valve 17 is opened, nitrogen flows in a pipe 18, atmospheric pressure of a gap 4 between the lower surface of a mask 1 and a resist film 3 slightly rises to life the mask 1 to generate a force for pressing down the film 3, and the distance of the gap 4 is widened slightly. When the valve 17 is closed, the original state is restored. When the valve 17 is periodically opened and closed, the atmospheric pressure in the gap 4 periodically varies, the pressure for lifting the mask 1 or the pressure P for pressing down the film 3 varies with opening or closing of the valve 17, and the distance of the gap 4 varies with changing of the applied pressure P. The intervals 4 between the mask 1 and the film 3 is varied slightly during exposure to move bright and dark fringes so that the film 3 is averaged with the result that the film 3 does not photosense in the form of bright or dark fringes.

Title: Antiskid control device
Inventor: HORIUCHI YASUSHI
IPC: B60T8/172
Filed: 1986-09-19
Abstract: PURPOSE:To enable a skid condition to be instantaneously eliminated, by controlling a brake pressure on the basis of a change rate of wheel deceleration and a slip rate of a wheel. CONSTITUTION:A change rate of wheel deceleration is obtained by detecting a wheel peripheral speed in a car body running system by a sensor 5 to be differentiated by a differentiator 6. While a slip rate is obtained in an arithmetic device 10 by said wheel peripheral speed and a vehicle running speed detected by a car body speed detector 7, and a pressure regulator 20, to which a pressure regulating signal is output from a control means 11, regulates a pressure of brake fluid applied to a wheel cylinder 3 from a master cylinder 2 is accordance with the depressing force of a brake pedal. Here the control means 11 increases the brake pressure, when the slip rate is less than the optimum value with the change rate of deceleration larger than 0, while decreases the brake pressure when the slip rate is larger than the optimum value further with the change rate of deceleration smaller than the proper acceleration. In this way, the running stability always improves by enabling a skid condition to be instantaneously further surely eliminated.

Title: Optical scanning device using aspherical hologram
Inventor: SHIOZAWA TAKAHIRO
IPC: G03H1/00
Filed: 1986-09-19
Abstract: PURPOSE:To improve aberrational characteristics and linearity characteristics by setting the linearity error of light which forms an image on a scanning surface below a specific value and finding a local ideal phase transfer function for minimizing its aberrations, and finding an aspherical hologram from the local ideal phase transfer function. CONSTITUTION:Reproduced light 11 is projected on the aspherical hologram 10 and diffracted light 12 which is diffracted by this aspherical hologram 10 forms its image on the scanning surface 4. The aspherical hologram 10 rotates around its center O, and consequently the light moves on the scanning surface 4 to make a scan. When coordinates fixed in a space based on the center O of the aspherical hologram 10 as its origin are denoted as (x, y, z) and coordinates fixed on the aspherical hologram 10 while having the same origin are denoted as (x', y', z'), the coordinate axes and coordinate axes (x', y', z') meet each other unless the aspherical hologram 10 rotates. This hologram 10 is rotated to set the linearity error of light which forms its image on the scanning surface below the specific value and the local ideal phase transfer function which minimizes the aberrations is found. Thus, an optical scanning device which has a small linearity error and small aberrations is obtained.
